Jaguar Mining Intercepts Wide High-Grade Gold Mineralization from Initial Growth Exploration at Turmalina; Confirms Extension to Principal Orebodies

TORONTO, Nov. 28, 2017 (Canada NewsWire via COMTEX) --

TSX: JAG

Jaguar Mining Inc. ("Jaguar" or the "Company") (TSX: JAG) today announced initial results from the first 18 underground drill holes (5,454m) from the Company's Growth Exploration Program at Turmalina Gold Mine ("Turmalina") in Minas Gerais, Brazil, targeting the down-plunge continuity of the principal mineralized Orebodies A and C (see press release September 20, 2017). Results reported are for the first 14 holes (4,368m) on Orebody A, as well as 4 holes (1,068m) on Orebody C, and represent approximately 50% completion of an overall exploration program of 11,355m. Three diamond drill rigs are currently focused on completing the remaining 50% of this program. Further results will be released over the coming months with an upgraded mineral resource expected to be published during 2018.

Highlights and Key Intercepts

    --  Drilling results include multiple intercepts with wide and
        high-grade mineralization and confirm significant depth
        extensions to principal Orebodies A and C that remain open for
        expansion.

    --  Orebody A key intercepts: 17.72g/t Au over 13.7m (ETW 10.2m)
        including 40.81g/t over 5.2m (ETW 3.87m), 4.46g/t Au over
        19.05m (ETW 11m) including 16.37g/t Au over 2.2m (ETW 1.27m)
        and 6.39g/t Au over 5.65m (ETW 5m) (see Table 1 and Appendix
        1).

    --  Orebody C key intercepts: 29.15g/t Au over 1.75m (ETW 1.65m),
        3.51g/t Au over 4.10m (ETW 3.95m) and 4.57g/t Au over 3.85m
        (ETW 3.46m), which is the deepest intercept on this orebody
        to-date close to level 9, or 300 m below current operational
        infrastructure on level 3. (see Table 2 and Appendix 2).

    --  Orebody A drill results demonstrate continuity of high-grade
        gold mineralization to below level 15 approximately 300m below
        the current deepest operations on level 11.

    --  Deepest intercept reported to date is on level 16 with 3.80g/t
        Au over 11.05m (ETW 4.30m) including 5.25g/t Au over 3.55m (ETW
        1.38m).

    --  The downward extension of Orebody C is ideally positioned
        approximately 250 meters away from the principal ramp
        infrastructure of Orebody A (see Figures 2 and 3).


Definitions: ETW - estimated true width g/t Au - grams per tonne gold m - metres

Rodney Lamond, President and Chief Executive Officer, Jaguar Mining commented "We are very pleased to announce these positive results and the successful start of our growth exploration drilling program at Turmalina. Drilling from the first 18 holes focused on targeting down-plunge extensions to the high-grade Orebody A at depth, while also targeting extensions of Orebody C at shallower depths. These results confirm significant wide, high-grade gold mineralization within the primary orebodies at Turmalina. The multiple high-grade intercepts validate the geological model and confirm significant upside potential to grow the resource base at Turmalina. To date in 2017, we have successfully completed more than 20,000 meters of a targeted diamond drilling exploration and growth program across of our core assets. Our priority was to focus on upgrading and converting our resources and on growth drilling to increase and add new resources. We look forward to reporting updated mineral resources and mineral reserves in early 2018 that will reflect the excellent results we have achieved throughout this year."

Growth Exploration Program Key Highlights

    --  Drilling completed to date has successfully intersected both
        Orebody A and Orebody C between Levels 11 to 15 and levels 5 to
        9 respectively.

    --  Results from initial step out holes on Orebody A include
        several wide, high-grade gold intercepts representing the
        thickened central portion of Orebody A, as well as quality
        intercepts from contiguous narrower parts of the Orebody A
        structure. In addition, the first four holes targeting depth
        extensions to Orebody C have demonstrated orebody continuity to
        level 9, approximately 300m below the current operational
        infrastructure on level 3. These positive results validate the
        projected mineralization plunge and grade envelopes well beyond
        current mine production infrastructure on both principal
        orebodies.

    --  Importantly, these intercepts were achieved from both targets
        in their respective predicted down-plunge projected positions
        up to 300m below current operational infrastructure and
        resource limits, and at grades and thicknesses consistent with
        historical production and resource grades. Grade, tonnage and
        ounces-per-vertical-metre are expected to be maintained at
        historical levels (see Figures 1, 2, 3 and 4).

    --  Intercept widths and grades vary, as expected, according to the
        location of the pierce points along the targeted structures
        that host Orebody A. The wider, higher-grade zones reflect a
        drill intersection cutting an area where the separate host
        shear structures that define this orebody merge. This
        consistent, wide, high-grade zone extends some 40m along
        strike, can attain widths in excess of 12m and has a plunge of
        50 degrees to the northeast. This wider zone (payshoot) is
        reflected above 30 GT (grade x thickness) on the GT plot (see
        Figure 1).

    --  Narrower intersections with more variable grades occur where
        pierce points are intersecting either one or two of the host
        shears, which may be separated by low grade mineralization or
        waste where these segments of the overall mineralized structure
        are manifested as distinct separate structures (see Figures 1
        and 2).

    --  Growth exploration drilling is initially targeting the
        down-plunge depth extensions to higher grades associated with
        the narrower southeast and thicker central portions of Orebody
        C identified for the first time earlier in 2017 (see press
        release February 8, 2017). Production development and infill
        drilling completed this year centred on levels 3 and 4
        confirmed and enhanced the drilled widths and grades on these
        levels.

    --  To guide the growth exploration drilling, intersections from
        infill and production--grade control drilling conducted by
        Jaguar during 2017 were used to prepare grade thickness models
        in conjunction with initial structural work to project this
        orebody to depth down plunge 300m vertically below level 3. The
        intercepts used to prepare the grade thickness plots on Figure4
        are tabulated in Appendix 3.


Jon Hill, Senior Expert Advisor (Geology and Exploration) to the Jaguar Mining Management Committee commented: "Today's excellent results demonstrate material extensions to both principal Orebodies A and C, clearly underpin the long-term future of Turmalina, and support the value of sustained investment in exploration. The results from Orebody C are particularly encouraging as only four holes have been completed to date, and these have sampled a relatively small portion of the known potential strike length of the mineralized horizon as observed closer to surface. We continue to explore this horizon going forward."

Drill Results and Intercepts -Turmalina

Drill results reported below and in Appendices 1 and 2 provide the potential to add substantial new mineral resources at Turmalina and include the following key intercepts:

Orebody A

    --  FTS1434 intercepted 4.71g/t Au over 9.80m (ETW 8.5m)

    --  FTS1473 intercepted 4.57g/t Au over 3.85m (ETW 3.46m)
  o (Including 7.75g/t over 2.1m (ETW 1.89m)


Please see Tables 1 and 2, Figures 1, 2, 3 and 4, and Appendices 1 and 2 for more details.

    --  Drilling is being undertaken from a hanging wall development
        drive specifically prepared and completed for this program on
        Level 10-1. Drilling targeting Orebody A is designed to
        intersect this orebody between Levels 12 to 16, up to 300m
        vertically below the current development (see Figures 1 and 2).

    --  At shallower levels, drilling is targeting projected
        down-plunge extensions to Orebody C, which, once confirmed,
        will allow access for mining from existing infrastructure
        between Levels 4 and 10 (see Figures 3 and 4).

    --  Regular updates on progress with results will be released over
        the coming months prior to reporting updated Mineral Resources
        in 2018.


Qualified Person

Scientific and technical information contained in this press release has been reviewed and approved by Jonathan Victor Hill, BSc (Hons) (Economic Geology - UCT), Senior Expert Advisor Geology and Exploration to the Jaguar Mining Management Committee, who is also an employee of Jaguar Mining Inc., and is a "qualified person" as defined by National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101").

Quality Control

Jaguar continues to use a quality-control program that includes insertion of blanks and commercial standards in order to ensure best practice in sampling and analysis.

HQ, NQ, and BQ size drill core is sawn in half with a diamond saw. Samples are selected for analysis in standard intervals according to geological characteristics such as lithology and hydrothermal alteration. All diamond drill hole collars are accurately surveyed using a Total Station instrument and down-hole deviations are surveyed using non-magnetic equipment (SPT Stockholm Precision Tools with GyroMasterTM Solid State North Seeker).

Mean grades are calculated using a variable lower grade cut-off (generally 0.5 g/t Au). No upper gold grade cut has been applied to the data. However, the requirement for assay top cutting will be assessed during future resource work.

Half of the sawed sample is forwarded to the analytical laboratory for analysis while the remaining half of the core is stored in a secure location. The drill core samples are transported in securely sealed bags and sent for physical preparation to the independent ALS Brasil (subsidiary of ALS Global) laboratory located in Vespasiano, Minas Gerais, Brazil. The analysis is conducted at ALS Global's respective facilities (fire assay are conducted by ALS Global in Lima, Peru, and multi-elementary analysis are conducted by ALS Global in Vancouver, Canada). ALS has accreditation in a global management system that meets all requirements of international standards ISO/IEC 17025:2005 and ISO 9001:2015. All major ALS geochemistry analytical laboratories are accredited to ISO/IEC 17025:2005 for specific analytical procedures.

The Iron Quadrangle

The Iron Quadrangle has been an area of mineral exploration dating back to the 16th century. The discovery in 1699-1701 of gold contaminated with iron and platinum-group metals in the southeastern corner of the Iron Quadrangle gave rise to the name of the town Ouro Preto (Black Gold). The Iron Quadrangle contains world-class multi-million-ounce gold deposits such as Morro Velho, Cuiabá, and São Bento. Jaguar holds the second largest gold land position in the Iron Quadrangle with just over 25,000 hectares.

Figure 1

Figure 1 shows the location of growth exploration diamond drill holes reported to date relative to the current mine infrastructure and the projected down-plunge position of Orebody A. The ongoing program is targeting mineralization between Levels 11 to 16 on Orebody A up to 300m vertically below current development. Grade thickness (GT) contours based on drilling results received to date and representative horizontal sections showing the positions of reported drill intersections relative to the projected orebody wireframe positions are also presented (see Figure 2).

Figure 2

Figure 2 shows representative horizontal sections on levels 10, 12 and 15, highlighting the positions of reported drill intersections relative to the projected Orebody A wireframe positions.

Figure 3

Figure 3 shows the location of growth exploration diamond drill holes reported relative to the current mine infrastructure and the projected down-plunge position of Orebody C. The program targeted mineralization between Levels 5 to9 on Orebody Cup to 300m vertically below current development. Grade thickness (GT) contours are based on drilling results received to date as well as historical drilling from operational areas on levels 3 and 4. Horizontal sections showing the positions of reported drill intersections relative to the projected orebody wireframe positions are presented in Figure 4 and Appendices 3 and 4.

Figure 4

Figure 4 shows representative horizontal sections on levels 4, 5 and 9, highlighting the positions of reported drill intersections relative to the projected Orebody C wireframe positions. For further details on level 4, see Appendix 4.
